Intended Use
The Bluebird Single-Use Respiratory Effort Belt is intended to measure respiratory effort to assist in the diagnosis of sleep disorders or sleep related respiratory disorders. The respiratory effort belt signals are suitable for connection to sleep/polysomnography (PSG) systems. The intended environments are hospitals, institutions, sleep clinics, or other test environments, including the patient's home. The Bluebird Single-Use Respiratory Effort Belt is intended for diagnostic purposes only on patients greater than 2 years of age and is not intended to be used as an apnea monitor.
Device Story
Bluebird Single-Use Respiratory Effort Belt measures chest/abdomen expansion/contraction during respiration; utilizes Respiratory Inductive Plethysmography (RIP) technology. Device consists of elastic belt with embedded sinusoidal copper wire coil; inductance changes as belt stretches. Connects to physiological recording equipment (PSG systems) via 1.5mm female touch-proof jacks. Used in hospitals, clinics, or home settings; operated by clinicians or technicians. Provides output signal proportional to stretch; assists clinicians in diagnosing sleep disorders. Passive device; no internal power source; signal processing performed by connected PSG recorder.
Clinical Evidence
Bench testing only. Comparative performance testing demonstrated equivalent respiratory effort signal output between the subject device and the predicate when connected to the same PSG recorder. Testing verified dimensional requirements, buckle functionality, and compatibility with standard PSG recording equipment.
Technological Characteristics
Respiratory Inductive Plethysmography (RIP) sensor. Materials: elastic fabric, plastic (polypropylene buckle), copper wire. Form factor: pre-sized elastic belt (various sizes). Connectivity: 1.5mm female touch-proof jacks (DIN 42 802 compliant). Passive device; no energy source. Single-use.
Indications for Use
Indicated for patients > 2 years of age to measure respiratory effort for diagnosis of sleep disorders or sleep-related respiratory disorders. Not for use as an apnea monitor.
Regulatory Classification
Identification

Dear Jason Ford:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

#### Device Description
The Bluebird Single-Use Respiratory Effort Belt (Bluebird) is used to measure chest and abdomen expansion and contraction during respiration. The sensor consists of a sinusoidal wire coil attached along the length of an elastic belt. The inductance of the sensor changes as the belt is stretched. The Bluebird is suitable for connection to the inputs of physiological recording equipment. The Bluebird measures inductance and generates an output signal proportional to the amount of stretch. The elastic belt is held in place by a quick release buckle with a cinch function and the belt is adjusted to fit snugly but comfortably. Electrical connection to the two ends of the embedded coil is through a 1.5mm female touch proof connection jack on each side of belt buckle. The materials are elastics and plastics used in the clothing industry, and fine gauge copper wire for the embedded coil.

## K242424 510(k) Summary
humidity Resistance EMC compliance Cleaning
is not required since the subject device is a single use device. EMC and operational testing is not required for the subject device and is mitigated by the PSG recording device requirements. Therefore, these differences do not affect the safety or efficacy of the subject device.
#### Performance Testing
Nonclinical tests were performed on the subject device in order to show the technological equivalency to the predicate device and to verify the compliance to design requirements. No special controls exist for this type of device. Device testing included dimensional requirements, continuity. belt buckle function, ability to connect the subject device to a standard PSG recording device, recorded respiratory effort signal quality, packaging testing and comparative performance testing to the predicate.
The comparative performance testing provided direct performance comparison to the actual recorded output signal of each device. Performance testing was performed for the Bluebird rip belt connected to a Cadwell recording device and simultaneously to an XactTrace belt, therefore both belts acting as passive devices, connected to the same Cadwell PSG recorder. The resulting waveforms are the same for both belts.
#### Conclusion
The passing results of the nonclinical tests and the technological and Indications for Use comparison demonstrate the Bluebird Single-Use Respiratory Effort Belt is substantially equivalent to the legally marketed predicate device.
